Advances in technology have opened new opportunities for people who are partially sighted or blind to be fully independent at work, in school, and at home. On the market today are optical scanners that "read" print, closed circuit television systems that magnify print or pictures, and an array of devices and software that work with standard personal computers ("PCs") to create large print, synthetic voice or Braille output.

When you consider purchasing an assistive device, especially one that is specialized, expensive, or may require training to use, there are some general points to keep in mind:

• Although the great majority of up-to-date computers can be used with assistive technology, before making a purchasing decision, be sure to check that the PC you select can be used with the assistive technology you plan to use. For example, in order to work well with most assistive hardware/software, a PC must have at least 256MB of RAM (512MB recommended).

• There is no device that is universal. What works for others may not work for you.

• Determine your needs. What do you want to be able to do with the equipment?

• If you are partially sighted, consult with your eye care specialist before purchasing any equipment. Your vision condition may make it easier or harder to use some devices, and it is best to determine that as early as possible.

• Get as much information as possible about the device and the different companies who make it.

• Make sure that any necessary software will work for you. Windows, and other software that relies on graphic features such as icons, have in the past been difficult for people with impaired vision to use. Recent developments in screen reading software have made this type of software more accessible for users of voice output, refreshable Braille, and screen magnification programs. However, it is still a good idea to consult a technology specialist to help you select software that works best for you.

• Arrange to test equipment before purchase.

• If training is needed to use the equipment, find out how it will be provided. Will the manufacturer provide training? If not, where can you get training? Is there a fee?

• Determine your budget. There may be a variety of devices and/or software that you can use, so get the one within your spending limit. Many devices are costly. Check with your state or private rehabilitation agency, state or local advocacy group, independent living center, or membership organization (such as the National Federation of the Blind or the American Council of the Blind) for advice on financial assistance.
